My kernel scripts to compile it in Gentoo systems

MyKernel

Gentoo kernel with root luks example

We create luks partition with cryptsetup

With blkid we can see created partitions UUID

/dev/nvme0n1p1: UUID="51F2-B573" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="3bb72034-0028-4b4b-a022-86dcf77991bf"
/dev/nvme0n1p2: UUID="e3905174-0bfc-406c-8958-8004cfec6528" TYPE="crypto_LUKS" PARTUUID="01037e81-d022-c041-a85e-6e872cbcb791"
/dev/mapper/root: UUID="ebc859bc-a777-4953-9c92-178c89b52222" BLOCK_SIZE="4096" TYPE="ext4"

Gentoo package install-kernel must have dracut USE

We edit /etc/dracut.conf

add_dracutmodules+=" crypt dm rootfs-block "
kernel_cmdline+=" root=UUID=ebc859bc-a777-4953-9c92-178c89b52222 rd.luks.uuid=e3905174-0bfc-406c-8958-8004cfec6528 "

We edit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="crypt_root=nvme0n1p2"
